Japan's Fair Trade Commission began a forced investigation on the morning of Oct 7 into four major brewers — Asahi Beer, Kirin Beer, Suntory and Sapporo Beer — on suspicion of violating the Antimonopoly Act through unreasonable restraint of trade over beer prices, according to multiple outlets. The companies are headquartered in Tokyo's Sumida, Nakano, Minato and Shibuya wards respectively. [ 1 , 3 , 4 , 5 , 6 , 8 , 14 , 18 ]
The four are suspected of coordinating wholesale prices charged to distributors such as supermarkets and restaurants over several years, including the size of increases and the timing of price revisions, according to people familiar with the matter cited by the outlets. Talks are said to have taken place at regular meetings of an industry body and at separate gatherings of the four companies afterwards — described by Mainichi Shimbun as a “behind-the-scenes” meeting — attended by section-manager-level sales staff. Mainichi reported the regular meetings involved five companies, including one regional brewer, while Jiji Press said the managers met periodically as part of an industry group activity called “Ikkikai”. The suspected price coordination covers beer, happoshu and third-category beer. [ 3 , 5 , 6 , 8 , 11 , 15 , 18 , 20 ]
The investigation is based on the commission's criminal investigation authority, which allows searches and seizures under court warrants, and the commission is proceeding with a criminal complaint to prosecutors in view. Yomiuri, Asahi, Sankei and Jiji all reported that this authority was last applied in September 2025, in a light oil cartel case. Sankei reported it was the first time the commission has used a forced investigation into food and beverage products. [ 5 , 6 , 8 , 18 ]
Outlets gave differing measures of the market involved. Yomiuri reported that the 2025 domestic market for beer-type beverages is expected to reach 1.6699 trillion yen, citing research firm Fuji Keizai, and that 2018 taxable shipment volumes were 37.4% for Asahi, 34.4% for Kirin, 16.0% for Suntory and 11.4% for Sapporo. Nikkei said the four hold more than 90% of the domestic beer market. Sankei cited National Tax Agency data putting domestic beer and happoshu sales in 2024 at about 1.6 trillion yen, while Jiji said the beer market is roughly 1 trillion yen and the happoshu market around 400 billion yen. [ 5 , 8 , 14 , 18 ]
The investigation follows repeated price increases by the brewers. Yomiuri reported that canned beer prices rose in October 2022 for the first time in 14 years, citing higher aluminium and other material costs, and that the companies raised prices again in April 2025 on raw material and logistics costs. From this month, a liquor tax revision cut the tax on beer while raising it on happoshu and third-category beer, Yomiuri reported. [ 5 ]
The four companies said they would cooperate fully with the investigation, according to Yomiuri, Jiji and Sankei. Nikkei reported selling pressure on beer-related shares, including Sapporo, following the reports. [ 5 , 16 , 18 , 19 ]
Why it matters
The four companies account for the overwhelming majority of Japan's beer-type beverage market, so any confirmed price coordination would have affected prices paid by supermarkets, restaurants and consumers. The use of the commission's criminal investigation authority, and the stated possibility of a criminal complaint, raises the prospect of penalties for the companies and individuals involved. For the industry, the case also puts scrutiny on the informal meetings where the commission says pricing information was exchanged.
Key facts

- The suspicion is that the four companies coordinated wholesale (shipment) prices for beer to distributors such as supermarkets and restaurants, including the size of increases and the timing of revisions. [ 3 , 5 , 8 , 18 ]
- The alleged coordination is said to have continued over several years, and the targets include beer, happoshu and third-category beer. [ 6 , 8 , 18 ]
- The investigation is based on the commission's criminal investigation authority, which allows searches and seizures under court warrants, and is being pursued with a criminal complaint to prosecutors in view. [ 5 , 6 , 8 , 18 ]
- The four companies said they would fully cooperate with the investigation. [ 5 , 18 , 19 ]
- The commission last applied its criminal investigation authority in September 2025, in a light oil cartel case. [ 5 , 6 , 18 ]

Confirmed by several sources
- The Fair Trade Commission conducted a forced investigation into four major brewers on suspicion of an Antimonopoly Act violation. [ 1 , 3 , 4 , 5 , 6 , 8 , 14 , 18 ]
- The companies subject to the investigation are Asahi Beer, Kirin Beer, Suntory and Sapporo Beer, all headquartered in Tokyo. [ 3 , 5 , 6 , 8 , 18 ]
- The investigation is based on the commission's criminal investigation authority and is being conducted with a criminal complaint to prosecutors in view. [ 5 , 6 , 8 , 18 ]
- The four companies are suspected of adjusting beer shipment prices over several years. [ 3 , 5 , 8 , 18 ]

Still unclear
- Whether the alleged cartel will be established and whether prosecutors will receive a criminal complaint. The documents describe an investigation in progress and say the commission is proceeding with a criminal complaint in view, not that one has been filed.
- The exact period of the alleged price coordination. Documents say only that it lasted several years or at least since several years ago, without giving dates.
- The role of the regional brewer mentioned by Mainichi Shimbun. One document says a fifth, unnamed regional brewer took part in the regular meetings, but does not say whether it is a target of the investigation.
- The size of the beer market, which documents state differently. Yomiuri, Sankei, Nikkei and Jiji give differing figures and scopes (beer-type beverages, beer and happoshu, beer alone) and cite different years and sources.
